Could you make one of these for snow and sand?

Very impressive system! Do you think you'll look into full boat support as well as ocean wave simulation?

A potential optimization for your scene capture component: Charlie (PrismaticaDev on youtube) was experimenting with optimizations because he has a persistent system that tracks grass interaction, sand trails, water etc. Turns out, if you use 2 render targets, blur them slightly, stagger their start times, and lerp between them on read using time in the material graph, you can get an acceptable result at very low update rates (he posted in his discord that his scene capture went from 30fps to 8fps and still looked great). Should speed things up if you do it correctly. I might not be explaining this well, so maybe you should shoot him a message about it.


2 questions:

-is it possible to sample height at a point? will a line trace pick up the ripple deformation, for example?
-is it possible to add gerstner waves to make the water itself look nicer?

Look cool but big minus no spline river
